As an important part of the building, the layout of the ventilation ducts in the basement has a key impact on the indoor air quality and comfort. Reasonable optimization of the direction of airflow organization based on the spatial structure is the core of achieving efficient ventilation.
First of all, the basement space needs to be carefully analyzed. For a long and narrow basement, a longitudinal ventilation layout can be adopted, and the main ventilation duct is set along the length direction, and the branch ducts are evenly distributed on both sides, so that the airflow can flow smoothly from one end to the other, reducing the dead corners of airflow. In a large square or rectangular basement, a circular or cross-shaped ventilation duct network should be constructed, with the main duct set in the central area and branch ducts radiating to the surrounding areas to form a uniform and stable airflow circulation to ensure that every corner can be effectively ventilated.
Secondly, consider the functional zoning of the basement. For example, in office areas or residential areas where people stay for a long time, ventilation ducts should be arranged in areas where people move frequently, and the air outlet should be avoided from blowing directly at people. Diffuser vents can be used to make the airflow soft and dispersed. For areas that generate heat or odor, such as equipment storage areas or storage rooms, ventilation ducts should be set up around these areas to increase ventilation volume so that heat and odor can be discharged in time and prevented from spreading to other areas.
In addition, the layout should be combined with obstacles in the basement. If there are structures such as columns and walls, the ventilation ducts should cleverly bypass or utilize these obstacles. The ducts can be installed along the edges of columns or walls, and the airflow can be guided to change direction and maintain a stable flow rate by reasonably setting elbows and reducers. For some large equipment that cannot be avoided, the method of partially raising or sinking the ducts can be adopted to ensure that the airflow can pass smoothly and maintain good organization.
In addition, the location and number of vents must also be considered. The air inlet should be set in a place with fresh air and no pollution, such as near outdoor green areas or away from pollution sources. The air outlet should be evenly distributed according to the spatial layout and airflow direction to avoid local airflow congestion or backflow. Through simulation software or actual testing, the location and number of vents are optimized and adjusted to achieve the best airflow organization effect.
In a word, the basement ventilation duct layout should comprehensively consider many factors such as space structure, functional zoning, obstacles and vents, and be carefully designed and planned to optimize the direction of airflow organization and create a healthy and comfortable air environment for the basement.
